Description
Technical field
The present invention relates to a kind of method for aligning of sheet metal strip, this sheet metal strip is transferred by straightener and being aligned thus along throughput direction, and in this straightener, sheet metal strip applies corrective force by a plurality of smoothing rolls in the direction perpendicular to the surface of sheet metal strip.In addition, the present invention relates to a kind of straightener.
Background technology
In the manufacturing and treatment facility of band steel, the common rolling of band steel is transported to the equipment place, so that following process or processing are put into feeding part then and carried out uncoiling and penetrate equipment in this way handling.The band steel is transfused in the equipment by uncoiling.For this reason, crooked band steel toe portion must align, so that the band steel can penetrate in the feeding part of equipment and can transport the waste material section of band steel toe portion when needed without barrier.
The quality of quality that the band steel is handled and band steel depend on can to what extent make the band steel of at first reeling become a kind of flat be the state on plane.Known for this reason have a straightener, makes by a plurality of smoothing rolls of effect on the band steel that to begin also be not that flat feeding belt steel becomes straight band steel state.
So when correcting, need guarantee after the aligning process finishes, to reach high as far as possible glacing flatness by suitable processing mode.In being designed to the straightener of roll leveller, use three to seven rollers usually.Above-mentioned correct roller can move or regulate perpendicular to the surface of band steel, so that the coupling belt steel thickness.For this reason, make electricity consumption servo drive or mechanical screw type jacking system, also use eccentric wheel sometimes.
EP1275446A2 discloses a kind of method of handling the transverse curvature of the band steel of eliminating to pass through continuously with a band steel treatment facility on the line at the band steel, wherein, transverse curvature is measured and is eliminated by the adjustable corrector roll of immersion depth in the zone of band steel processing line.Eliminating transverse curvature directly carries out in the band steel processing line zone of band steel treatment facility front.
In order to proofread and correct the deviation of the glacing flatness of sheet metal strip in the straightener, DE10230449A1 has proposed the assay method of the Position Control size of smoothing roll.According to this method, at first from the measured value of strip flatness deviation, determine an actual coefficients that is fit to the shape function of expression ribbon shape, determine target factor from this actual coefficients then, at last target factor is converted to the Position Control amount of smoothing roll.
DE3840016A1 discloses a kind of method for aligning of sheet metal strip, wherein, measures straightening force at least and adjust the smoothing roll position according to the value of measuring on one of smoothing roll of roll leveller.Here regulation is measured the vertical straightening force on each smoothing roll that affacts straightener or roll-type bearing or the frame separately, and automatically transfers smoothing roll according to these values of measuring again in the scope that produces the pressure variation.
Method for aligning according to the sheet metal strip of DE3308616C2, sheet metal strip transports between the upper and lower smoothing roll that staggers mutually and the repeatedly alternating bending of degree of deformation by constantly reducing, and smoothing roll can be adjusted by the classification of a predetermined deformation degree relatively according to steel plate cross section and steel plate nominal intensity.Particularly in the process of aligning, measure the straightening force on the smoothing roll, determine corresponding armor plate strength from straightening force and steel plate cross section, and constantly proofread and correct the drafts of smoothing roll according to corresponding armor plate strength.
Structure solution that other of the straightener of sheet metal strip is special and method of work thereof can be learnt from EP0765196B1, EP0182062B1, WO02/076649A1, DE3414486C2, DE4216686A1, EP0035009B1 and JP11192510.
A problem of not considering up to now is, though considered the material property of sheet metal strip to be aligned, does not reach satisfied leveling effect sometimes because thickness of strip fluctuates.Particularly not rolling band steel end is aligned more and be a problem, because band steel toe portion or afterbody fluctuate on thickness seriously.The band steel the whole longitudinal axis present wedge shape even step-like varied in thickness, so to reach one repeatably the aligning process be extremely difficult.
Summary of the invention
The objective of the invention is to propose a kind of method for aligning and straightener of sheet metal strip, can overcome above-mentioned shortcoming simply with this method and straightener, in other words, though sheet metal strip along also guaranteeing desirable leveling effect under the situation of the thickness catastrophic fluctuation of its longitudinal axis.
This purpose is to realize by a kind of method with following feature of the present invention: determined the thickness of this band before sheet metal strip enters straightener, and along the normal direction of sheet metal strip surface smoothing roll is applied drafts according to the thickness of determining.
For thickness measure can be carried out simply, be preferably in the interior enforcement of the enough distances thickness measure of smoothing roll front.So according to improvement project, depressing of smoothing roll in the distance of considering smoothing roll front thickness measure with along regulating in time under the situation of the transporting velocity of throughput direction sheet metal strip, that is determine that by measuring distance before the smoothing roll and transporting velocity one is depressed the idle period of considering when regulating at smoothing roll.
In order to ensure band at the high end product quality aspect its glacing flatness, another scheme is to carry out one-shot measurement on the outlet side of straightener, determine with this measurement the sheet metal strip corrected from ideal line promptly perpendicular to the trend that arches upward and the deviation on the desired center plane in the direction of sheet metal strip surface, and in the normal direction of sheet metal strip surface, smoothing roll is applied drafts according to trend of arching upward and deviation, make sheet metal strip straight as far as possible after the aligning process finishes.
Wherein, especially can determine the above-mentioned trend that arches upward and deviation by the displacement measurement that on the outlet side sheet metal strip, carries out.
Another alternative plan or additional be also can determine this arch upward trend and deviation by the power measurement.In this case, preferably carry out the power measurement by a smoothing roll that is arranged in outlet side.Another kind of solution is, independently surveys roller with respect to smoothing roll and carries out power and measure by one or more.
The another improvement of the inventive method can realize like this: in the aligning process of straightener, measure the size of the straightening force that is applied by smoothing roll, the straightening force that same basis is measured applies drafts to smoothing roll in the normal direction of sheet metal strip surface.So just can carry out the comparison of the theory-actual forces relevant with material.
The straightener of the aligning sheet metal strip that is proposed has a plurality of smoothing rolls, these smoothing rolls can apply straightening force along the normal direction of sheet metal strip surface, sheet metal strip is transferred by this straightener and is aligned along certain throughput direction, the present invention is provided with the mechanism of measuring metal tape thickness, and this arrangement of mechanism enters the porch of straightener or be positioned at the inlet front on throughput direction at sheet metal strip.
Throughput direction can reverse when needed.This band of crossing at the aligning of straightener back is significant when not satisfying desired glacing flatness requirement.For this reason, the drafts between straightener entrance side and the straightener outlet side is symmetrical, and promptly the drafts in opposite throughput direction is equivalent to the drafts of throughput direction.Like this, the band head just can carry out the aligning second time like this in opposite throughput direction, makes it reach best leveling effect at the entrance side of straightener.Then, selectively in direction of advance, align for the third time again or the band head continues operation by the machine opened.
The servoelement of position adjustments preferably is set, and this servoelement is applicable in the direction perpendicular to the surface of sheet metal strip depresses smoothing roll.It is particularly advantageous that the servoelement of this position adjustments is designed to the hydraulic plunger cylinder system.
At last, can be provided with the sheet metal strip aligned in perpendicular to the direction of sheet metal strip surface from the trend that arches upward of ideal line and the measuring mechanism of deviation, this measuring mechanism is arranged in sheet metal strip and is positioned at the outlet back from exit that straightener comes out or at throughput direction.This measuring mechanism can independently be surveyed roller with respect to smoothing roll by one or two (upper and lower) and form.
Even under the situation of the thickness catastrophic fluctuation of the sheet metal strip that will align, also can reach good leveling effect, improved the quality of the sheet metal strip of being produced so on the whole or simplified the manufacturing of band and made process more reliable by the present invention.

One embodiment of the present of invention shown in the drawings.
The diagrammatic side view of the end of Fig. 1 a and Fig. 1 b sheet metal strip;
Fig. 2 is used to align the schematic diagram of the straightener of sheet metal strip;
The similar view of Fig. 3 and Fig. 2 shows most important regulated value;
Fig. 4 implements the part of the regulating loop that the aligning process uses;
Fig. 5 implements the detail drawing of the regulating loop that the aligning process uses.
The specific embodiment
Fig. 1 a and Fig. 1 b show a kind of side view that should carry out the sheet metal strip 1 of straightening processing, there is shown a kind of zone of head of not rolled strip.Typically, the thickness d of sheet metal strip 1 all is inconstant in the whole longitudinal axis of the band that is equivalent to throughput direction R.The situation of Fig. 1 a is, sheet metal strip 1 is wedge shape and extends, and Fig. 1 b represents that then the thickness of sheet metal strip is the situation that stairstepping extends.
The aligning of this sheet metal strip is difficult especially, and has only straightener shown in Figure 22 just might align effectively.
The sheet metal strip 1 of outlet 4 back of straightener 2 should strive for reaching the shape of representing with solid line (ideal line).But as do not take a large amount of measures, then sheet metal strip 1 generally all can produce the trend of arching upward, this arch upward trend with the deviation x-of this ideal line up or down-represent, shown in dotted line.In order to prevent this situation, must take such measure: the thickness d of in throughput direction R, measuring sheet metal strip in the mechanism 6 of the suitable well-known forms of sensor of arranged in front of straightener inlet 7 own.Distance between sensor 6 and the smoothing roll center-in throughput direction R, measure-represent with b.
The thickness d of sensor 6 measurement sheet metal strips 1 and the value that will measure are delivered to an adjusting device 9.Upper straightening roll 3 is regulated according to the thickness d of measuring to the drafts a of following smoothing roll 3 by servoelement 8.Wherein considered the idle period, this idle period represents that sheet metal strip 1 moves to the time of the position consumption of smoothing roll 3 from the measuring position.Under the situation of known distance b and transporting velocity v, this idle period is to determine easily.
In order to obtain the right value of drafts a.In adjusting device 9, store a kind of corresponding algorithm, or infer the correct and suitable value of yield point and infer the drafts a that regulates by servoelement 8 thus by the curvilinear motion of storage.
Arrange that in the outlet 4 of straightener is surveyed a roller 5, in order to the deviation x of detection sheet metal strip 1 from ideal position.The deviation of measuring also is sent to adjusting device 9, and this device is correspondingly proofreaied and correct drafts a by the algorithm or the curvilinear motion of its internal memory.Detection roller 5 that need not be independent, last smoothing roll 3 ' that also can be used in the throughput direction R carries out this measurement.
Fig. 3 represents the adjusting schematic diagram of the adjusting drafts a of smoothing roll 3.Adjusting device 9 is measured thickness d as input parameter from sensor 6 acquisition sheet metal strips 1.In addition, also be transfused in this adjusting device by a power gauge head or piezometry 10 a straightening force F that measure.The sheet metal strip of in the direction N of outlet 4 perpendicular to the surface of sheet metal strip 1 of straightener 2, measuring 1 from the deviation x of ideal line as another input parameter input regulating device 9 in.In addition, schematically illustrated the band data D of supplying regulator 9, these data are stored in the database 17.
Store a kind of algorithm or form in adjusting device 9, this algorithm is inferred the drafts a that best leveling effect is required according to thickness d, deviation x, straightening force F and band data D, and (F D) represents for d, x with functional relation a=f for this.
Figure 4 illustrates some details of regulation technology: power gauge head or pressure detector 10 are measured the pressure p that affacts in the hydraulic servo element 8, and this pressure can be converted into straightening force by a route marker 14.Store band data D in database 17, the best of promptly for example making the used material of sheet metal strip 1 becomes the information of offset.The best theoretical value of straightening force can access and compare in the value of subtracter 18 with actual measurement from database 17.Difference signal is handled the back by in the next subtracter 19 of a limiter 12 inputs in the draught control mechanism 11 of a for example stack at a slow speed.In order to obtain different running statuses, draught control mechanism 11 also can be designed to cut-off, and for example the switch by counter stress adjuster 11 cut-offs.Taking from the optimum value of theoretical drafts a of database 17 and the measured value of drafts a also imports in this draught control mechanism.Difference signal is transfused to adjuster 13, and this adjuster is to the regulated value of servoelement 8 output drafts a.
Other details of regulating schematic diagram can be as can be seen from Figure 5: both stored family of curves in the database 17 here, and stored form again, they the are given best yield point St of material when straightening processing of sheet metal strip 1 to be processed.Can find family of curves in the left area of database 17, these families of curves provide existing yield point St to belt steel thickness d given in advance.Can consider hot-strip yield point and the cold-strip steel yield point (the possible initial point and the terminal point of family of curves) made by the raw material of cold-rolled process in this case.Sensor 6 provides the actual value of the thickness d of sheet metal strip 1.(see figure 2) under the situation of known transporting velocity v and distance b can determine that sheet metal strip 1 arrives the required time of position of smoothing roll 3 from the thickness measure position.This uses an idle running T in Fig. 5
TFunction as speed v is represented.
In the zone shown in database 17 lefts, determine desirable yield point with actual one-tenth-value thickness 1/10, and with its input database 17 in the zone shown in right-hand.Can determine required drafts a and with respect to the straightening force F (perpendicular to throughput direction R) of the width B of sheet metal strip 1 according to thickness d by the data of storage or algorithm.
This value and developed width B multiply each other in multiplier 20 and draw theoretical straightening force F
S011This theoretical value is transfused in the adjuster 21, deducts actual straightening power F in a subtraction position of this adjuster back
IstThis actual straightening power is determined by power gauge head or pressure detector 10 and route marker 14.Difference is transfused in the adjuster 22, and this adjuster is transferred to a subtraction position 23 by limiter 12 with its signal.
The target correction value of drafts a is from database 17 and by an adjuster 24 same subtraction positions 23 that arrive.The value of measuring of actual drafts a is also imported this place.Signal difference input (master) adjuster 13, this adjuster provides the regulated value of drafts a and sends it to servoelement 8.
Only show the situation of a servoelement 8 among the figure, although a servoelement 8 preferably respectively is set in the both sides of girder steel 15 and 16.In this case, circuit structure doubles.
That is in an embodiment, carry out continuous belt steel thickness and measure, its result is sent to the hydraulic cylinder of position adjustments by described regulating system.Actual belt steel thickness is measured by thickness measure sensor 6, and required for this reason regulated value is provided by the hydraulic cylinder of position adjustments.The regulating loop of sealing has been guaranteed depressing continuously of smoothing roll, thereby has eliminated the belt steel thickness influence.
For the influence of the intensity of eliminating sheet metal strip 1, as long as a kind of method of orientation adjustment is as a result also measured the deviation from the outlet side of ideal position.From deviation measure or the exerting pressure of power gauge head or pressure detector 10 deducibility go out and must how to regulate again, just can reach a desirable leveling effect.Thereby reaching the sheet metal strip 1 that comes out from straightener 2 does not almost arch upward.In addition, measure adjusting pressure in the hydraulic cylinder.This pressure deducibility goes out material property, particularly when belt steel thickness when being known.These data also can be used for calculating location and regulate and be integrated in this regulating loop.
Regulated value and variation thereof collect in the database 17 and can be used for the preset of straightener 2 when other sheet metal strip 1 of aligning or use as initial value when a new equipment puts into operation.
(to the mensuration of thickness d, deviation x and straightening force F) also can be above-mentioned sensor, and, for example use optical measurement sensors with other sensor arbitrarily.
